An automatic centering clutch, as shown in fig. 1 to 5, comprises a motor 4, a speed reducer 5, a transmission chain wheel 6, a cylinder fixing seat 7, a cylinder 8 and a sliding bearing 3 which are arranged on a machine base 10, wherein a spline shaft 14 is arranged on the machine base 10 through the sliding bearing 3, the spline shaft 14 is matched with a driven chain wheel 11 which is arranged on the machine base 10 through a driven chain wheel fixing seat 12, and the driven chain wheel 11 is arranged on the spline shaft 14 through a spline groove in a sliding fit manner; the left side end of the spline shaft 14 forms a power output end 2, the power output end 2 comprises a sleeve, an aligning shaft 15 is installed in the sleeve in a matching mode through a compression spring 16, the outer side end of the aligning shaft 15 forms a conical head, and the end face of the outer side end of the sleeve forms an engaging buckle structure 13; the engaging buckle structure 13 is a conventional structure. A spline shaft fixing sleeve 9 is fixedly sleeved at the right side end of the spline shaft 14 through a set screw, a groove is arranged in the right side end of the spline shaft 14, a thrust bearing 18 is arranged in the groove in a matched manner, a spline sleeve 17 is sleeved in the spline shaft fixing sleeve 9 in a matched manner, a spline is arranged on the axial outer wall of the spline sleeve 17, a spline tooth groove is arranged in the spline shaft fixing sleeve, the spline shaft fixing sleeve 9 is matched with the spline sleeve 17, and the spline sleeve 17 is fixedly arranged at the end part of a piston rod of the air cylinder 8 and is abutted against the thrust bearing 18; the cylinder 8 and the spline shaft 14 are coaxially arranged and fixedly mounted on a right cylinder fixing seat 7 of the machine base 10; the end part of a rotating shaft of the speed reducer 5 is provided with a transmission chain wheel 6, and the transmission chain wheel 6 drives a driven chain wheel 11 to drive a spline shaft 14 to rotate through chain transmission.

And (3) power meshing process: the power transmission is realized through the engagement of the power output end 2 and the load end 1 in the power engagement process, and in the engagement process: the centering shaft 15 with a conical head can realize the automatic alignment function of the mechanism. Meanwhile, the spring 16 connected to the rear end of the spindle 15 can not only reduce the impact on the spindle 15 at the moment of meshing, but also assist the mechanism to quickly break away from unloading power. The power output end 2 and the load end 1 both adopt an engagement buckle form, the engagement process is stable, and the impact force is small.

The power axial and radial transmission process comprises the following steps: axial meshing power transmission: in the working process, the spline shaft 14 moves axially along with the movement of the air cylinder 8, and meanwhile, the driven chain wheel 11 is limited by the fixed seat 12 to move, so that the driven chain wheel is always in an ideal position during transmission of the two chain wheels.
